quantitative analysis of silver in ore
[Quantitative Analysis of Copper Impurity in Silver ...
A quantitative analysis of copper impurity in silver jewellery can be realized by using orthogonal dualwavelength dualpulse laserablation laserinduced breakdown spectroscopy. A calibration curve of copper was successfully built based on internal standard method while selecting nm line of silver as internal standard.
